Application May 24, 1949, Serial No. 95,115

2 Claims.

My present invention relates to an improved book marker of the typedesigned to be detachably secured to the book cover of the book by aclamp member and having connected thereto by a flexible connecter a fiatelongated marker formed with an adjustable line indicator.

The marker of my invention in addition to its obvious utility will havesuitable ornamentation and may be made of suitable material such as thevarious plastic substances now available and may be made in anydesirable color.

In the accompanying drawings I have illus trated one complete example ofthe physical embodiment of my invention according to the best mode Ihave thus far devised, but it will be understood that various changesand alterations may be made in the exemplified structure within thescope of the appended claims.

In the drawings:

Fig. 1 is a front elevational View of the marker of my invention.

Fig. 2 is a side elevational view thereof.

Fig. 3 is a sectional view at line 33 of Fig. 1.

Fig. 4 is a rear view of the clamp member.

Fig. 5 is a sectional view thereof at line 5-5 of Fig. 4.

Fig. 6 is a perspective View of the movable line marker.

Referring now to the drawings wherein I have illustrated the presentpreferred embodiment of my invention I employ a clamp plate 2 foldedupon itself at t to form the rear spring clamp 6, offset at 8, and whichextends at 10 below the lower extremity of the front plate. Near theupper fold 4, the plate and the spring clamp are apertured to receive aring 12 to which is secured a chain I4.

This chain [4 is attached as b a ring IE to the upper post [8 of themarker 20 which post is enclosed by the curved arms 22.

The marker 20 consists of an elongated flat bar pointed as at 20 at itslower end for easy insertion into the book, and the marker has aconnected edge slot 26 and side slot 28 to receive the enlarged flangebar 30 and the reduced plate 2 32 of the pointer 34. The pointer issnugly fitted into the slots of the marker and the frictional contactbetween the pointer and the slot walls will retain the pointer in thedesired position.

The pointer may well be of blending or contrasting color, and the chainmay be of suitable length to fit most books.

By the use of the marker of my invention the device will be securelyattached to the book by the spring clamp and may easily be placedbetween the desired pages with the pointer set at the proper line forlater reference.

Having thus fully described my invention a what I claim as new anddesire to secure by Letters Patent is:

1. A book mark comprising an elongated flat bar having two faces and twoside edges, 21. first longitudinal slot in said bar open to both facesthereof, a second longitudinal slot in one side edge of the barcommunicating with the first slot, a pointer having a reduced centralplate portion and an enlarged end flange portion at each end of saidcentral plate portion, said pointer being slidably mounted in said slotsso that one enlarged flange portion is in said first slot the centralplate portion is in said second slot and the other enlarged flangeportion engages the outer surface of the side edge in which said secondslot is provided.

2. A book mark as in claim 1 wherein a book cover engaging clamp isflexibly connected with one end of the bar.
